Take a look at this Hyperion battleship that my corp mates took down last night. What's wrong with it? Anyone?
It looked good at first glance to me. Best named blasters, tech II buffer tank is a little light for me but I understand not everyone wanting trimarks instead of CCC rigs. Then I did a double-take at the warp disruptor AND warp scrambler. And no web. None.
Now, I am a firm believer that if you setup a ship intended for gangs that you don't necessarily need to cover the dps/tank/tackle trinity on every ship. But I'm also very aware of the limitations of my weaponry and I try to compensate for that as much as possible.
From Eve Fitting Tool, a Hyperion with that blaster cannon and a tech II tracking computer with tracking script and perfect skills has a tracking of 0.07475 radians per second. From my Masterclass article on Tracking you know that when you multiply that number by a range and you can see the maximum speed of a target orbiting that range that you can follow fast enough to hit. For 0.07475 that means about 150 m/s at 2000 meters and 225 m/s at 3000 meters.
I can fly a Myrmidon without an afterburner or MWD at 158 m/s and that is with rigs and armour slowing me down. So essentially I pull into a 1500 meter orbit and the Hyperion is helpless. Warp Scrambler won't help you... you are dead.
That Hyperion screams for a webber. One web and he's pounding those battlecruisers and at least has a chance at surivival or taking one down. In a gang situation I'd had a web even if I was flying with two Rapier pilots. Its simply a matter of making sure your shit can hit.
